Kennametal 1097561 Indexable Threading Toolholder

Product Description

The KENNAMETAL 1097561 is an external, right-hand indexable threading toolholder from the Top Notch series, designed for precision threading and grooving operations on metal lathes and turning centers. It accepts N.3L inserts secured by a clamp-style holding method, providing repeatable positioning and rigid support during cut. The shank measures 0.75 x 0.75 inches (19.05 x 19.05 mm), and the overall length is 4.5 inches (114.30 mm). The maximum depth of cut is 0.210 inches (5.33 mm). This toolholder is installed by machinists and tool-and-die professionals in job shop and production turning environments.

The 1097561 is suited for external threading and grooving applications on CNC lathes and manual turning machines in both job shop and production settings. The NE toolholder style and Top Notch series designation make this a recognized fit for facilities already standardized on compatible Top Notch insert families. The clamp holding method allows quick insert indexing without removing the toolholder from the machine, reducing setup time during high-cycle runs. It functions as a multi-use tool capable of handling both threading and grooving operations in a single holder.
